Wearable electronic device comprising sensor, and method by which electronic device processes touch signal

Abstract

A wearable electronic device is provided. The wearable electronic device includes a housing, which includes a first part at least partially exposed to an outside to receive a touch by being seated on at least a portion of a body of a user, and a second part extending from the first part, and configured to be concealed by the first part by being inserted into an ear canal of the user, the first part including a first touch area facing a first direction and a second touch area disposed on at least a portion of a lateral edge of the first part, adjacent to the first touch area and facing a second direction, a main touch sensor disposed below the first touch area, an auxiliary touch sensor disposed below the second touch area, and a circuit board disposed inside the housing, and including a processor electrically connected to the main touch sensor and the auxiliary touch sensor and configured to control an operation state of the wearable electronic device based on touch information obtained from the main touch sensor and the auxiliary touch sensor, wherein the auxiliary touch sensor includes a first auxiliary touch sensor and a second auxiliary touch sensor, disposed below the second touch area, wherein the processor is further configured to maintain the operation state of the wearable electronic device, when a touch sensitivity measured at least a portion of the first auxiliary touch sensor and the second auxiliary touch sensor is equal to or greater than a first threshold, and wherein the processor is further configured to change the operation state of the wearable electronic device, when touch sensitivities measured at the first auxiliary touch sensor and the second auxiliary touch sensor are less than the first threshold and a touch sensitivity measured at the main touch sensor is equal to or greater than a second threshold.
